The Plug-On Module "Motor control" can be plugged easily on the interface connector
(24-pin) of the PLC-Trainer 1200. The speed of the assembled DC motor can initially
be controlled by a potentiometer. By slide switch "PMW" the pulse-width modulation
can be activated. Then the speed of the motor can be continuously controlled with
the help of the SIMATIC S7-1200 from 0 to Max (e.g. controlled ramp). By switching
a further switch on the Plug-On Module to "Ext." the DC motor can be continuously
controlled by an external voltage from 0 to 10V/DC. The perforated disc on the driving
shaft passes through two fork light barriers. So a real detection of direction and
speed is possible. The rotation is visually indicated by two integrated LEDs.
